Since a couple of days ago, the Forum now uses CKE5. The problem I'm seeing is that it's impossible to select the Styles: Code block. Those are grayed out:

And if you choose the PHP style, this is equivalent to the old "inline PHP" style, and the result includes blank lines in between each line of code.

In short, with CKE5 it has become impossible to paste well-formatted code.
BTW: is there any way to use markdown in the forum. This would be A-MA-ZING!
